DlLATlNG-NOZZLE.

SPECIFICATION forming part of Letters Patent No. 728,175, dated May 12, 1903.

Application filed August 23, 1901. Serial No. 73,096- (No model.)

To all whom it may concern:

Be it known that I, GUSTAV OTTO, a citizen of the United States, residing at Jersey City, New Jersey, have invented certain new and useful Improvements in Dilating-Nozzles, of which the following is a specificatiomwherein reference is made to the accompanying drawings, forming part thereof.

My invention relates to dilating-nozzles; and the object of said invention is to provide a simple and efficient device which can be used either as a plain or dilating nozzle and which is capable of a variety of uses. Thus the device may be used as a vaginal, urethral, uterine, rectal, or phymosis dilator as well'as a syringe-nozzle.

To these and other ends which will hereinafter appear my invention consists in the novel arrangements and combination of parts to be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a side view of one form of device embodying my inventibn, the parts being shown in the contracted position. Fig. 2 is a like view of thesame with the parts shown in the expanded position. Fig. 3 is a detail front or end view of the device. Fig. 41s a detail face view of what I term the expansion-plate.

The device comprises a tubular nozzle-sec tion A, which terminates at one end in a nozzle a and at the opposite end with suitable "means I) for making connection with a rubber tube or other suitable means for supplying the nozzle. The nozzle 0. is preferably of bulbous form and constitutes a rose-nozzle. The nozzle-section A may be screw-threaded throughout a portion of its extent, as indicated at c, for cooperation with a suitable thumb-nut d. The thumb-nut 01 when employed is adapted to bear against one face of a collar e, which is freely movable on the nozzle-section. This collar c has rigidly secured thereto a plurality of spring dilatingarms f, each arm being preferably formed with a loop at the outer end, as indicated in the drawings. These arms f surround nozzlesection and are bent, as indicated at g, for purposes which will hereinafter appear. Secured to the nozzle-section in the rear of the bulbous nozzle is what I term an expansionplate B. This expansion-plate may be perforated, as indicated at h, to permit a backflow whenthe nozzle is in use, and guideways '6 are likewise provided for cooperation with the dilating-arms f. In the present instance these guides are in the nature of depressions in the periphery of the expansion-plate and an arm is adapted to slide in each depression, and the arms are in this manner prevented from being accidentally bent or deflected laterally from the position which they are intended to occupy. In other words, the arms are at all times maintained by the guides in the proper position one with relation to another, whether the arms be in the position indicated in Fig. 1 or inthepositionshown in Fig. 2 or in any of the intermediate positions. The curved portion g :of each dilating-arm, hearing as it does against the edges, of the plate B, will act as a cam, and when the thumb-nut d is screwed on nozzle-section A or the collar e is pushed forward the dilating arms are moved from the position shown in Fig. 1 to that indicated in Fig. 2.

It will be observed that when the parts are in the position illustrated in Fig. 2 the inner face of the collar 6' will be brought into contact with a fixed sleeve 3' on the nozzle-section, which acts as a stop to limit further forward movement of the collar, and consequently prevent the dilating-arms from being expanded farther. It will likewise be seen that when the dilating-arms'are contracted, as shown in Fig. 1, the nozzle-head is fully exposed, so that it may be used as an ordinary nozzle. When, however, the dilator is employed, the head of the nozzle will be withdrawn between the arms,where the openings in the nozzle are fully protected and are not liable to become clogged. It will also be observed that the rounded head of the nozzle presents an even surface with the dilatingarms when the parts are in the contracted position, so that but little obstruction is presented for the insertion of the device.

The thumb-nut d is particularly available where the instrument is employed as a rectal dilator or dilator-nozzle, because of the great pressure that is necessarily employed to expand the dilator. vents any chance of the dilator accidentally collapsing when in use.

Furthermore, the nut pre- 10g;

By reason of the fact that the nozzle-head is forced forward to the exposed position when the dilator is contracted there is no opportunity afforded for the ends of the dilating-arms to pinch or unduly compress the tender parts of the body when the instrument is in use.

The construction of the dilating-nozzle is such that it is adapted for a variety of uses. It may be used, for instance, as an ordinary nozzle when the parts are in the position indicated in Fig. 1, and as a dilating-nozzle it maybe used for the vagina, rectum, or urethra, and it may likewise be used as a phymosis dilator-nozzle, in which latter event it may be advisable for better efficiency to slightly change the contour of the dilatingarms at the outer ends.

Having described my invention, what I claim, and desire to secure by Letters Patent, 1s-

1. In a device of the character described, the combination of a nozzle-section, a movable collar thereon, a stop to limit the move ment of the collar, spring dilating-arms carried by and rigidly secured to the collar and surrounding the nozzle-section, a perforated expansion-plate against which the dilatingarms bear and through the perforations in which the backflow may pass and mechanical means for moving the collar to expand the arms, the head of the nozzle being, contiguous to the ends of the arms when the arms are contracted.

2. In a device of the character described, the combination of a nozzle-section, a movable collar thereon, spring dilating-arms carried by and rigidly secured to the collar and surrounding the nozzle-section, a perforated expansion-plate against which the dilatingarms bear and through the perforations in which the backtiow may pass, screw-th reads on the nozzle-section and a thumbscrew which cooperates with the threads on the nozzle-section and with the collar to move the latter in order to expand the dilating-arms.

3. In a device of the character described, the combination of a nozzle-section, a movable collar thereon, a stop to limit the move ment of the collar, spring dilating-arms carried by and rigidly secured to the collar and surrounding" the nozzle-section, a perforated expansion-plate against which the dilating arms bear, guides which prevent an accidental lateral deflection of the dilating-arms, screw-threads on the nozzle-section and a thumb screw which cooperates with the threads on the nozzle-section and with the collar to move the latter in order to expand the dilating-arms.

4;. In a device of the character described, the combination of a nozzlesection, a movable collar on the nozzlesection, a stop to limit the outward movement of the collar, spring dilating-arms carried by and rigidly secured to the collar and surrounding the nozzle-sec tion, the head of the nozzle being projected forward beyond the ends of the arms and contiguous thereto when they are contracted, an expansion-plate having unobstructed openings therein through which the backflow may pass and against which expansion-plate the dilating-arms bear, peripheral guides in the plate that prevent an accidental lateral deflection of the dilating-arms, screw-threads on the nozzle-section, and a thumb-screw which cooperates with the threads on the nozzle'section and with the collar to move the latter in order to expand the dilating-arms.

GUSTAV OTTO.
